Systems and methods for electromagnetic (EM) distortion detection and compensation are disclosed. In one aspect, the system includes an instrument, the system configured to: determine a reference position of the distal end of the instrument at a first time based on EM location data, determine that the distal end of the instrument at a second time is static, and determine that the EM location data at the second time is indicative of a position of the distal end of the instrument having changed from the reference position by greater than a threshold distance. The system is further configured to: determine a current offset based on the distance between the position at the second time and the reference position at the first time, and determine a compensated position of the distal end of the instrument based on the EM location data and the current offset.

The user interface housing includes a locking body coupled to a body of the user interface housing and has a flange configured to engage an edge of the user interface. A latch mechanism includes a flexible body coupled to a rear side of the locking body. The latch mechanism is configured to selectively secure the locking body in a position. A shelf is coupled to a lower portion of the body of the user interface housing. The shelf has stoppers operably coupled to the shelf. The stoppers are adjustable along a horizontal plane to define different widths.

The present disclosure provides a mounting assembly for attaching medical equipment to a patient table. In one particular embodiment, the present disclosure provides a mounting assembly for attaching a magnetic field generator to a patient table. The mounting assembly allows for the secure attachment of the magnetic field generator to the patient table while also allowing for easy adjustment of the positioning and location of the magnetic field generator, even after the patient is on the table. In many embodiments the mounting assembly is comprised of a mounting apparatus that attaches directly to the patient table and first and second side rails that attach to the magnetic field generator and are configured to slidably attach to the mounting apparatus. In some embodiments, the mounting apparatus and side rails are constructed of a material that provides little or no interference with the magnetic field generator.

A femoral lift apparatus for an operating table having a side rail, the apparatus engageable with the femur of a patient. The apparatus includes a lift mountable to the side rail. An extension arm is receivable on the lift, the extension arm extending transversely from the lift when the extension arm is received on the lift. A plurality of apertures can be defined along the extension arm, and a femoral hook can be receivable in one of the apertures in the extension arm, the femoral hook having a hook end shaped to be received under and contour the femur of the patient positioned on the operating table when the lift is mounted to the side rail of the table, the extension arm is received on the lift, and the femoral hook is received in one of the apertures of the extension arm.

A system for positioning a patient before, during or after a medical procedure can include an arm assembly and a surgical drape for use with the arm assembly. The surgical drape can be configured to be placed around a surgical site where an operative procedure is to be conducted. The surgical drape includes a transparent viewing window, multiple handle covers, and an expandable opening on the top side of the surgical drape. Additionally, the surgical drape may also include adhesive components on the bottom side of the drape that may be independently removed in order to affix the drape around a surgical site.

A surgical instrument includes an end effector, a shaft assembly, an actuation driver, and an actuation assembly. The end effector includes first and second jaws. At least one of the first and second jaws is configured to move relative to the other of the first and second jaws to compress tissue therebetween. The shaft assembly extends proximally from the end effector. The shaft assembly includes a closure member extending along a longitudinal axis. The actuation driver is configured to configured to receive a motor output from a motor. The actuation assembly is operatively coupled with the actuation driver and the closure member. The actuation assembly includes a translating member configured to translate together with the closure member along the longitudinal axis a predetermined distance using the actuation driver such that the closure member applies a predetermined closure force to the first and second jaws corresponding to the predetermined distance.

An ultrasonic surgical instrument including an end effector having an ultrasonic blade, a shaft assembly that defines a longitudinal axis proximally extending from the end effector and an ultrasonic transducer assembly proximally extending from an acoustic waveguide in communication with the ultrasonic blade. The ultrasonic surgical instrument also includes a housing proximally projecting from the shaft assembly such that the ultrasonic transducer assembly is positioned within the housing and a carrier moveably supports the ultrasonic transducer assembly along the longitudinal axis. The carrier collectively moves the ultrasonic transducer assembly, the acoustic waveguide, and the end effector relative to the housing from a proximal, retracted position to a distal, extended position, for inserting the ultrasonic blade into a patient. The ultrasonic surgical instrument also includes an electrical cable extending through the housing at a cable port that transmits electrical communication with the ultrasonic transducer assembly.

A multi-directional, equalizer clamp device is disclosed that provides, via a single action, a way to lock multiple objects that may be disposed in different numerous directions. The clamp may also achieve clamping using numerous force factors, and may be configured to attach and secure objects, such as pins, to the side rail of a support and/or operating table via a single-point of operation. The clamp device comprises upper and lower body portions which are configured to clamp to a side rail along a primary clamping direction, and are further configured to receive objects and clamp them along a secondary clamping direction. The clamp device further comprises a control assembly, such as a knob, to facilitate and achieve simultaneous clamping along both primary and secondary clamping directions at a single point of control.

A patient securing overlay is provided that includes a sheet of fabric for supporting a patient's torso on a surgical table. The sheet of fabric has an upper surface configured to face the patient and a lower surface configured to face a surgical table mattress or underbody support. The sheet of fabric includes friction enhancing elements applied to at least a portion of the upper surface thereof. The sheet of fabric can include an extension at a foot end of the sheet of fabric that provides material to be tucked under a foot end of the surgical table mattress or underbody support for securing the foot end of the sheet of fabric to the surgical table mattress or underbody support. The extension can include one or more friction enhancing elements.

A robotic surgical tool comprises a handle having a first end and a second end, a lead screw and at least one spline extendable between the first and second ends of the handle, and a carriage movably mountable to the lead screw at a carriage nut. The carriage includes an elevator layer and one or more additional layers removably coupled to the elevator layer. An elongate shaft may be provided that extends distally from the one or more additional layers and penetrates the elevator layer and the first end when the one or more additional layers are coupled to the elevator layer. An end effector may be arranged at a distal end of the elongate shaft.
